ionic bond

Examples of ionic bond in the following topics:

• Ionic Bonding and Electron Transfer

  • An ionic bond results from the transfer of an electron from a metal atom to a non-metal atom.
  • Ionic bonding is a type of chemical bond in which valence electrons are lost from one atom and gained by another.
  • An ionic bond is based on attractive electrostatic forces between two ions of opposite charge.
  • Ionic bonds involve a cation and an anion.
  • Ionic bonds differ from covalent bonds.

• Ionic vs Covalent Bond Character

  • The bond formed between any two atoms is not a purely ionic bond.
  • The larger the difference, the more ionic the nature of the bond.
  • In the conventional presentation, bonds are designated as ionic when the ionic aspect is greater than the covalent aspect of the bond.
  • This bond is considered to have characteristics of both covalent and ionic bonds.
  • Discuss the idea that, in nature, bonds exhibit characteristics of both ionic and covalent bonds

• Types of Bonds

  • Ionic bonds can form between nonmetals and metals, while covalent bonds form when electrons are shared between two nonmetals.
  • An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions.
  • Pure ionic bonding cannot exist: all ionic compounds have some degree of covalent bonding.
  • Thus, an ionic bond is considered a bond where the ionic character is greater than the covalent character.
  • Bonds with partially ionic and partially covalent character are called polar covalent bonds.

• Percent Ionic Character and Bond Angle

  • Chemical bonds are more varied than terminology might suggest; they exist on a spectrum between purely ionic and purely covalent bonds.
  • The ionic bonding model is useful for many purposes, however.
  • There is nothing wrong with using the term "ionic bond" to describe the interactions between the atoms in the very small class of "ionic solids" such as LiF and NaCl.
  • Does this make an ionic bond, a covalent bond, or something in between?
  • Recognize the differences between the theoretical and observed properties of ionic bonds.

• Ionic Bonds

  • Ionic bonds are a subset of chemical bonds that result from the transfer of valence electrons, typically between a metal and a nonmetal.
  • Ionic bonds are a class of chemical bonds that result from the exchange of one or more valence electrons from one atom, typically a metal, to another, typically a nonmetal.
  • This electron exchange results in an electrostatic attraction between the two atoms called an ionic bond.
  • Ionic bonds are also formed when there is a large electronegativity difference between two atoms.
  • The subscript two indicates that there are two fluorines that are ionically bonded to magnesium.

• Comparison between Covalent and Ionic Compounds

  • Ionic bonding occurs when there is a large difference in electronegativity between two atoms.
  • More than one electron can be donated and received in an ionic bond.
  • Some examples of compounds with ionic bonding include NaCl, KI, MgCl2.
  • Attraction of the oppositely charged ions is the ionic bond between Na and F.
  • Identify element pairs which are likely to form ionic or covalent bonds

• Introduction to Bonding

  • These bonds include both strong intramolecular interactions, such as covalent and ionic bonds.
  • Finally, for atoms with the largest electronegativity differences (such as metals bonding with nonmetals), the bonding interaction is called ionic, and the valence electrons are typically represented as being transferred from the metal atom to the nonmetal.
  • The two oppositely charged ions attract each other to form an ionic compound.
  • Covalent interactions are directional and depend on orbital overlap, while ionic interactions have no particular directionality.
  • Ionic compounds, though composed of strong bonding interactions, tend to form brittle crystalline lattices.

• Covalent Bonds

  • Covalent bonding interactions include sigma-bonding (σ) and pi-bonding (π).
  • Double bonds occur when four electrons are shared between the two atoms and consist of one sigma bond and one pi bond.
  • Unlike an ionic bond, a covalent bond is stronger between two atoms with similar electronegativity.
  • Ionic solids are generally characterized by high melting and boiling points along with brittle, crystalline structures.
  • Unlike ionic compounds, they are often not soluble in water and do not conduct electricity when solubilized.

• Formulas of Ionic Compounds

  • Ionic bonds are formed by the transfer of one or more valence electrons between atoms, typically between metals and nonmetals.
  • When sodium donates a valence electron to fluorine to become sodium fluoride, that is an example of ionic bond formation.
  • Ionic compounds can be described using chemical formulas, which represent the ratios of interacting elements that are found in the ionic solid or salt.
  • Polyatomic ions are a set of covalently bonded atoms that have an overall charge, making them an ion.

• Non-Ionic Reactions

  • With few exceptions, the multitude of reactions discussed in this and other introductory texts are classified as ionic reactions.
  • By this we mean that nucleophilic and electrophilic sites in reacting molecules bond to each other.
  • Ionic reactions normally occur in solution, and changes in solvents may have dramatic consequences.
  • In contrast to ionic reactions, both free radical and pericyclic reactions may occur in the gas phase, as well as in solution in various solvents.
  • Also, these nonionic reactions are more tolerant of spectator functional groups than are many ionic reactions.
